To shut the VM down, you can either perform a "shutdown -h now" inside the VM, or use the destroyVm function:

someuser@tashi:~$ tashi destroyVm --instance foobar

At the moment, shutdownVm does not function properly with Qemu/KVM. The VMM does not emulate this operation correctly. destroyVm is the same as unplugging a physical machine and should only be used on non-persistent VMs or when all else fails.

The basic workflow, if you're creating a new VM, is:

Copy the old i386-hardy.qcow2 (or amd64-hardy.qcow2) to a new file (i386-hardy-<username>.qcow2, for example).

Boot the VM in persistent mode (so writes in the VM are committed -- do this by appending ":true" to the image name)
